Check if Spark is really checking for updates even if that option is turned off
It was reported in the blog, that Spark will check for updates even with Check for updates option disabled. I will have to install Spark 2.6.1 and wait for 2.6.2 release.
Though i wasn't able to reproduce this with 2.6.1 on Windows 7. My colleague just got a popup about new version (he is on a nightly 2.6.1 build) and "check for updates" option is disabled.
closing down all 2.6.3 fixes
